![]() These numbers were negative? Let's think about it, if negative, negative, negative, negative. ![]() ![]() What if I had four numbers here? What if I had times, What if I had times d here? And if I told you all of But let's keep on doing, we said, look if all of them are negative, then this thing would be negative, but that's because I And then a negative times a positive, different signs, is going If I said, "There's other ways "that I can make the product negative." If a is, let's say that a, actually let me just write it this way. This whole thing is going to be negative. So this one, if a, b, andĬ are all less than zero, then the product, a, b, c is going to be less than zero as well. Positive times a negative, which is going to be a negative. So a negative times a negative, a times b, if you do that first, and we can when we multiply these numbers. What is this product going to be equal to? Well you're going to have a Let me actually write, let me write, a, b, and c, a, b, and c, they're all What if a, b, and c were all negative? Well if there were all negative, If I were to tell you that they were all negative numbers. Times b times c is going "to be positive." "A times b would be positive,Īnd that times c is positive." Now what would happen Were all positive numbers, then you say, "OK a Were to multiply a times, and now I'm going to What we might expect? So let's say that we But I was just thinking about what happens if we multiply or divide three things, or four things, or five things, or n things together, Now all of these, we thought about if we're only multiplying A negative divided byĪ negative is positive. And here I wrote it for multiplication, but it also applies to division. ![]() Negative times a positive, that also would give So if you have a positive times a negative that would give you a negative number. Get a negative number, is if you multiply or divide That that was also going to be equal to a positive number. You had the same sign, a negative times a negative, Well that, of course, is going to be equal to a positive number that you saw that even before you learned about negative numbers. I'm just writing "pos" short for positive. Positive and negative numbers, we saw, well look, if you have a positive number times a positive number. 0 is neutral, so it's neither positive nor may also be necessary to say an integer is basically a number.- When we first learned to multiply and divide A negative integer is an integer below 0. Negative integers are preceded with a "-" sign except for 0 because -0=0.The set of positive integers and the set of negative integers when used by themselves act the same way under addition (they are just spelt a little differently)3+3=6-3-3=(-3)+(-3)=(-6)They act differently under multiplication though.4*5=20(-4)*(-5)=20 (not -20)but (-4)*5=4*(-5)=-20I THINK THE ANSWER IS NATURAL NUMBERpositive integers are numbers with a value greater than zero (0) and negative integers are numbers with a value less than zero (0)The set of counting numbers: 1, 2, 3, 4, 5 and so on.A positive integer is an integer above 0. 0,1,2,3,4,5.) and negative means less than or equal to 0 (eg. Positive means greater than or equal to 0 (eg. Positive and Negative are adjectives that describe the integer. These negative numbers are steps backwards on a number line.Here are more opinions and answers from other FAQ Farmers:An integer is any whole number that doesn't contain anything beyond (to the right of) the decimal point. Negative integers are the "opposite" of counting numbers. Positive integers are also called "natural" or "counting" numbers. It is sometimes called "non-negative," but it is not positive. x - x = x + (-x) = (-x) + x = 0).Also -(-x)=xDifference Between Positive and Negative IntegersZero IS an integer, but it is neither positive or negative. and 0.Zero is the additive identity and for any integer x its additive inverse is -x (i.e. Integers form an algebraic group under addition and are closed under multiplication.The integers are the natural numbers (also called counting numbers) 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11. The integers is a larger set because it includes the negatives ofthe counting numbers-1, -2, -3, -4, -5, -6, -7, -8, -9, -10, -11. IntegersThe integers are a special set of numbers often called whole numbers.Whole numbers, however, consist of the counting numbers 1,2,3,4,5,6,7,8,9,10,11.along with zero. What is the difference between positive integers and negative integers?
